@RandomMrdan I thought “yanno” was the gross slang for “you know” Just seems strange that the OP would choose a New Guinean name for her example lol.
I think it more or less stems from a natural desire to dance around topics. For they may be delicate or potentially insulting. Perhaps it’s a way to “buy some time” if you will, in order to think what to say next. For example, often times when someone repeats a question you just asked them, even though they are standing in close distance and you spoke loudly and clear, is because they’re trying to figure out what they should say next and want to avoid an awkward silence. (side note, this also means that often times they’re lying or unable to give you an accurate answer).
The thing that really bothers me though, is when people use long, drawn out sentances with plenty of words that almost no one uses in everyday conversation, when a quicker and more basic choice of speech would do, just so people assume their abnormally intelligent.
for example. “Regrettably I am disinclined to acquiesce your request but I am dualy most appreciative”
when you could just say “no thanks, bud”
That may have been slightly exagerated for effect but it drives me up a wall when people insist on doing that.
